Hi, all
I get a question for ISI ( inter symbol interference) in optical link.
In Razavi'S book,<design of integrated circuits for optical communications> P65, Fig4.2 (b)
It says that if the bandwidth of the receiver is 1/4 of the data rate, then voltage decrease due to ISI is roughly 0.2*Vpp.
However, in Saeckinger's Book, < broadband circuits for optical fiber communication>, P59
It says that if the bandwidth of the receiver is 1/3 of the data rate, the voltage decrease due to ISI is 0.5*Vpp.
I was wondering which one is right? Or they are both right and I am wrong.
